A full facial respiratory mask assembly comprising a frame and a cushion, the cushion including a frame-connecting portion, a face-contacting portion and a gusset portion between the frame-connecting portion and the face-contacting portion, the gusset portion including a nasal bridge perimetrical region (16-1) and a mouth perimetrical region (16-2), the nasal bridge perimetrical region extending laterally outwardly to a lesser width (at W1) than the mouth perimetrical region extends (at W2), so that less force is applied at the patient’s nasal bridge region.
